CALCULATING-MACHINE.

Application filed August 21, 1911. Serial No. 645,259.

To all whom it may concern:

Be it known that I, J OHN C. WVAHL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Calculating-Machines, of which the following is a specification.

My invention is intended for the easier calculating of numbers printed in a hori zontal line. y

In ,Patent No. 893,717, issued to me on July 21, 1908, there is shown a calculating attachment to a typewriter which is able to add numbers arranged in a horizontal line. This is accomplished by the reciprocating of the totalizer in front of the master wheel. For the printing of numbers, the carriage moves'on continually in the same direction to the left. For the calculating of the various decimal places of the same number, the totalizer also moves on in the same direction in front of the master wheel. But between two different numbers, the carriage moves on in the same direction to the left, while the totalizer is reciprocated and brought back to the right, and located in the proper position for the new number. The carriage and totalizer then again move in unison for the printing and calculating of the next number.

It is quite customary to employ a tabulator in connection with a calculatingattachment to a typewriter. The ta'bulator is operated once for each number, and its operation results in the proper locating of the carriage for the printing of the number in its proper place. In the above cited patent, the reciprocating of the totalizer is accomplished by the carriage of the typewriter. One of the objects of my invention is the reciprocating of the totalizer by means of the tabulato-r keys instead of by the carriage.

The invention is illustrated by the accompanying drawings, of which Figure 1. is a front elevation of the mechanism as mounted upon a typewriter.

Fig. 2. is an elevation from the right side, showing the mechanism mounted upon a typewriter.

Fig. 3. is a view of some of the parts in a difi'erent position.

Fig. 4. shows some of the parts by themselves to more clearly illustrate their construction.

1, is a set of tabulator keys, 23.

.Fig. 5. is a side elevation of some of the parts.

Figs. 6., 7., 8., and 9., show details.

As the actual construction and operation of a typewriter inclusive of keys, type levers, type bars, carriage, escapement, etc., is very old and well-known in the art, and is to be found inany machine on the market, and as the presence of all of these parts in the drawing would help to confuse rather than to clarify, they have been omitted therefrom, Of course, they are supposed to be present in the actual machine.

In these drawings, 1 represents the framework of the typewriter and calculating machine, upon which is mounted the carriage, 2, in the usual manner. Travelin in unison with the carriage, 2, is a bar 3, 4 igs. 1, 2, 4,

said bar, 3, fastened to the carriage in any suitable manner. The bar, 3, is provided with a series of apertures or notches, 4. The function of the bar and notches is to support one or more engager pieces, 5. These engagerg are intended to engage and to move thel-totalizer, as will be explained below. Each one of these engagers is rovided with finger pieces, 7 (Fig. 9), an an extension 8, to enter one of the notches, 4:, to be ac curately located upon said bar, and notch 9, to engage a proJection from the totalizer. The edges of metal at the side of notch 9 are beveled, at 10, 10, and at 11, 11, for the readier engagement with the projection on the totalizer.

Mounted upon abar, 22, in the framework, Each one of these is connected by its link, 24, to its lever, 25. These levers, 25, are rotatably mounted upon a shaft, 26. Each lever 25 at its upper end is in engagement with a pin, 27, which pin is rigidly fastened into a sector, 28. These sectors, 28, are all rotatably mounted upon a shaft, 29, fastened in the framework. Meshing with each of these sectors, 28, is a mating sector, 30. These mating sectors: are rotatably mounted upon a shaft 31, also mounted upon the framework. The depressing of the tabulator key, 23, by means of the intermediate parts above mentioned therefore results in the rotating of the mating sectors, 28 and 30about their respective axes. and this rotating takes plat- 2 in an upward direction, looking at Mounted in hearings in the framework is a shaft 35 to which is rigidly attached a set of double arms, 36 (Figs. 2 and 8.)

There is one of these double arms, 36, for each of the gear mates, 28 and 30. Each double arm, 36, is provided at its two ends with rollers, 37, 37, and these rollers c051)- eratc with circular dwells, 38, formed by the upper portions of the gears mates 28 and 30. The upward rotating of the gear mates, 28 and 30, results in the striking of one of the circular dwells, 38, against its cooperating roller, 37. The particular circular dwell, 38, which first strikes its cooperating roller, 37, pushes that roller away and rotates its supporting arm 36 and therefore also shaft 35. -And this continues until the other roller 37 strikes the other circular dwell 38. The parts are so shaped that in this position which is shown in Fig. 3, there is no crowding and no superfluous space. The result therefore is that the motion of the gear mates 28 and definitely locates the cooperating double arm 36, and shaft 35, and after this definite locating has been accomplished, the gearmates, 28 and 30 are free to continue in their upward motion, the rollers, 37, 37, riding on their respective circular dwells 38, 38, above mentioned.

An examination of Fig. 1 and more particularly of Fig. 2 will show that the said arms 36 are mounted upon shaft 35, not in the same plane, but in a spiral, and the result is that the dwell position of each one of the arms 36 brings the shaft in a definite and different position. The depression of any tabulator key, therefore, results in locating the shaft in a definite position depending on the tahulator key.

lxigidly fastened to the shaft 35 is an arm 40 which is connected by a link 41 to a lever 42 pivot-ally mounted upon the framework. This lever 42 in turn is connected with a link 43 which in turn is connected to a lever ll. again pivotallv mounted upon the framework, and this lever it is again connected to a link 45 which in turn is connected to the totalizer 46. The rotation of the shaft 35 about its axis by means of matin gears 28 and 30 above mentioned thcrefore results in the motion of the totalizer 46 upon its supports 47, 47, and the definite locating of shaft 35 also results in the definite locating of the totalizer 46. And thus finally the depressing of a tabulator key results in the definite locating of the total-. izer it; in a position dependent upon the value of the particular tabulator key.-

Cach lever 25 above mentioned has an arm 50 extending therefrom. and under all of these arms is a shaft 51 which is supported by the end pieces 52 mounted upon a shaft 53. which is supported in the frame. work. The tension spring 50 fastened at one end to one of the arms 52, and at its other to the framework, tends to hold the shaft 51 in its up position in contact with the arms 50. The shaft 53 has fastened at its end an arm 55, which arm has a pin 56 extending therefrom, and working in the slot of the lever 57, which is pivotally mounted upon the frame Work. The lever 57 in turn has a slot 58 which operates a pin 59, mounted in a lever 60. This lever (50 is supported upon the shaft 31 previously mentioned. The lever 60 at its upper end is connected to a link 61 which in turn is connected at its other end to a lever 62 pivotally mounted upon the framework. And this lever 62 at its other end is connected to a. link 63 which in turn is connected to a lever 64, also pivotally mounted upon the frame work. The upper end of the lever 64, is connected to the disengaging plate (55 (Figs. 1, 2, 4, 5, and (3). The disengaging plate 65 has two diagonal slots (36, (36, through which are passed screws 67, (37, into the framework. The disengaging plate ()5 has its upper portion formed into a disengaging bar 68. there being a slot (39 cut below that. The depressing of any of the tabulating keys 23 and the consequent rotation of the lever 25 about its axis 26 results in the driving of the shaft 51 by means of arm 50 and the consequent rotation of the shaft 53 ,upon its center. This in turn by means of the mechanism just described results in the pulling of the plate (35 to the right.

The plate 65 because of the diagonal slots (36 above mentioned therefore moves down carrying down bar (58, and the purpose of this motion will be immediately explained. The totalizer 46 is provided with an engaging plate 80 mounted in its framework. This engaging plate 80 is provided with a tension spring 81 fastened with its one end to the engaging platc.80 and with its other end to the framework of the totalizer. The engaging plate 80 is formed at its back, looking at Figs. 2 and 5, into an engaging tongue 82, and this engaging tongue therefore has a constant tendency to move upward, and it is prevented from moving too far by contact with stop 83 fastened in the framework of the totalizer. The tongue 82 is shaped to fit within slot 9 of cngager 5 previously mentioned. so that whenever the tongue 82 is entered within slot 9 of engage]- 5, and the carriage of the typewriter is moved. then bar 3, engages engager tongue 82, and particularly the totalizer 46 are moved along therewith. This occurs during the printing and calculating of the various decimal places constituting one number.

As the carriage of the typewriter is moved along carrying the totalizer -in the manner just described, the two being connected by the. mechanism just explained. and this motion of the carriage (JUlltllHlts, the iotalizer upon the totalizer.

is carried far enough to the left (Figs. 1 and 4) to have its tongue 82 ride under the bevel 90 of plate 91 (Figs. 1, l, and T). The tongue 82 is therefore depressed and forced out of slot 9 of engager 5, and engager and carriage are therefore free to continue in motion to the left without moving the totalizer along. The totalizer is left at rest at the left side of its zone of travel. As the carriage continues farther, the other engagers 5 pass over the engager tongue 82, but the latter will be too far below them to be engaged by them.

An examination of Figs. 1, 4, and T will show that the plate 91 is provided with another bevel 92 at its right side which operates upon the engager tongue 82 in a manner similar to the bevel 90. The carriage of the typewriter is thus able to impart to the totalizer only a limited motion constituting the zone of reciprocation of the totalizer.

An examination of Figs. 1, l, 5, and (i will show that the tongue 82 of engaging plate 80 extends through the slot 9 of the plate 65. The depressing of plate 65 and the consequent depressing of the disengag ing bar 68 results in the depressing of 'tongue '82 and the consequent removal of said tongue out of reach of slot 9 of the engager 5. Fig. 4 shows the parts in this position, This is the function of the disengaging plate 65.

In the operation of the machine, tongue 82 is within the slot 9 while the numeral keys of the typewriter and calculating machine are operated. The type will print upon the paper and the master wheel .will operate Between the printing of each two figures, the carriage and totalizer will advance one step.- As soon as the last figure of the number has been printed and calculated, the operator will depress the tabulator key corresponding to the highest decimal place of the next number. This depressing of the tabulator key results in the release of the carriage by the ordinary tabulator mechanism. The carriage will therefore proceed to the left and be stopped by the tabulator stop as is usual. But the same movement, namely the de ressing of the tabulator key just mentionec, will now produce two additional results. One is the pulling of plate .65 to the right and conseuently the disengaging of the totalizer rom its previously engaged engager 5, and the other is the locating of the totalizer by means of the gear mates 28 and 30 in the position corresponding to the value of the tabulator key depressed. As long as the operator keeps the tabulator key depressed, the tongue 82 also will remain depressed and will not enter the slot of the next engager 9, which next engager has now been brought over the engaging tongue 82 by the mot-ion of the carriage produced because of writer, known as the Gorin tabul-ator.

The construction of the tabulator is' not a part of this invention and therefore has not been illustrated. There. are many tabulators on the market, for instance the one used in connection with the Remington ty lee connection to the tabulator which is completely located-at the back of the typewriter and not shown in any ofthe drawings, is by means of links 95, joined to levers 25 shown in the lower right hand corner of Fig. 2.

Attention is drawn to the difference in the operation of the mechanism here described and the mechanism in the above cited Patent, No. 893,717. In said patent, as the carriage of the typewriter moves from right to left, it engages the reciprocating portion, carrying it along through its zone of travel at the end of which it is released and returns under the influence of its spring to its previous location. In the steady motion to the left of the type-writer carriage,

the reciprocating portion of the calculating machine would therefore be given a number of reciprocations at the end of each one of which it would come in violent contact with a stop upon the carriage of the typewriter. The consequent jarring is very injurious and it has been found that this hammering continually loosens the screws and rivets, making it very difficult to keep the mechanism in order. By comparison with the mechanism described in'this specification, it will be seen that this jarring under the influence of a sprin has been eliminated, the totalizer being %rou ht to'its new position under the influence o" the pressure of the finger of the operator which of course is not vio- Y lent.

Again, should the typewriter be used for ordinary correspondence work and not for calculating, then naturally the tabulator would not be used, and therefore the total izer having once been located at either extreme of the zone of travel will now be simultaneously and automatically in alocation where its parts are out of reach of the carriage parts. It will therefore remain at rest and not be subject to any wear and tear during any time except during the actual calculating time.

In Patent No. 893,717, it has been shown that the totalizer returns to its previous position under the influence of a spring, and during the calculating is carried along b the typewriter carriage. In order that this may be readily accomplished. it has been found to be necessary to strengthen the spring operating the typewriter carriage. This.

results in a material hardening of the touch of the keys. In the mechanism described in this application, no extra return sp ing is required, and therefore no resultant strengthening of the carriage spring. Consequently the typewriter keys are not burdened with any extra load and their touch remains unimpaired.

In the drawings accompanying this specification and in the .mechanism described, there has been shown a reciprocating totalizer. This is the form in which the calculating machine has been put on the market in connection with the Remington typewriter. Of course it is understood that should the typewriter be of a different class, for instance a book typewriter like the Elliott-Fisher machine, then the mechanism would naturally be changed therewith and the totalizer Would. probably be stationary while the parts above described as stationary would reciprocate. In fact, calculating .machines in connection with typewriters might loosely be sub-divided into three classes:

1. Those in which the master wheel is stationary While the totalizer travels relatively thereto.

Those in which the totalizer is stationary While the master wheel travels relatively thereto.

3. Those in which there is no master wheel proper, its place having been taken by other mechanisms, as some sort of traveling trigger, determining the place of the calculation.

But in all of these classes, there is always some piece traveling relatively to another, and the position of this piece determines the decimal place of calculating in the calculating machine. I therefore call this traveling piece the decimal carriage. This decimal carriage may therefore be a totalizer, a master wheel, or a. trigger, the name decimal carriage being applied to it because of its function of determining the decimal place of the calculating, independent of other additional functions it may possess. In this machine, the decimal carriage is the traveling totalizer.

In this specification, the tabulator has been shown as one with a set of keys, being very similar therein to the ordinary Gorin tabulator on the market. But there are other ta'bulators of a different nature now on the market which differ from the Gorin in that they do not have a set of keys, but that one key is brought to any one of a plurality of positions. It is quite evident that without departing from the spirit of my invention it would be possible to change the mechanism to conform with this other tabulat-or, or with tabulators of even a different nature. The spirit of my invention resides in the fact that the operation of the tabulator determines the location of the decimal carriage, independent of any connection of the decimal -arriage with the printing carriage of the typewriter.
